This book seeks to set out the principles of Progressive Judaism and apply those principles to contemporary society and culture, the world of today in which Progressive Judaism and its adherents must find their moral bearings. Reconciling their beliefs with an ever-changing world is not a new experience for Jews. One of this book's underlying assertions is that Judaism has constantly adapted itself to meet the challenges posed to it by the need to survive in evolving societies - had it not done so, this ancient religion would long since have been written out of history.
